I am planning on buying a new 16gig iPhone through AT&T next week and before deciding this, I was looking for a used 3G 16gig iPhone to compare prices and came across many ads saying that they were selling a "Chinese Version" iPhone. These "Chinese Version" iPhones seemed to be less expensive and they were described as having the same features and abilities as the U.S. version. (maybe not truthfully) Has anyone on here come across one of these "Chinese" version iPhones? Does anyone know what exactly is different compared to the normal Apple iPhone sold through Apple stores and AT&T retailers here in the U.S.? I figured they were just iPhone clones or knock offs and not actually made by Apple, but I'm still curious what is different if they actually are made by Apple. Does anyone know?
